[0022] In this embodiment, the storage bin 1 is used to store heavy metal solidifying agents (lime, calcium polysulfide, etc.). This is the basic component for storing solidifying agents in the entire device, ensuring a sufficient supply of solidifying agents and providing the necessary material basis for subsequent remediation work. The distribution cylinder 2 is used for discharging solidifying agents in batches. Through reasonable design, the distribution cylinder 2 can evenly and quantitatively discharge solidifying agents into the farmland, avoiding waste and excessive concentration of solidifying agents, and improving the treatment effect. The soil turning roller 4 is used to turn the soil and mix the heavy metal solidifying agents. The rotation of the soil turning roller 4 can penetrate deep into the soil, thoroughly mixing the solidifying agents with the soil, thereby achieving... To effectively fix heavy metals in the soil and reduce their migration and bioavailability, the distributing rod 17 is rotatably installed inside the distributing cylinder 2. The isolation plate 18 installed on it is used to assist in the distribution of the metal solidifying agent. This design can ensure that the solidifying agent is discharged more evenly, avoiding local concentrations that are too high or too low, and further improving the treatment effect.

The stirring component is used to prevent the solidifying agent from clumping or agglomerating during storage, ensuring the looseness and fluidity of the solidifying agent, thereby improving its use effect.

[0023] In a further preferred embodiment of the present invention, the stirring assembly includes: a drive shaft 5 rotatably mounted inside the storage tank 1 and extending outside the storage tank 1; a protective shell 6 fixed inside the storage tank 1 and rotatably sleeved outside the drive shaft 5; a stirring rod 7 rotatably mounted on the protective shell 6 for stirring the heavy metal curing agent; and a bevel gear 8 fixed on the stirring rod 7 and the drive shaft 5 and meshing with each other for transmitting power.

[0024] In this embodiment, the drive shaft 5 serves as the power input component of the mixing assembly. The portion extending outside the storage tank 1 can be connected to a drive device (such as a motor) to provide the power required for mixing. The design of the protective shell 6 not only provides support and protection for the drive shaft 5 but also ensures the stable operation of the mixing assembly within the storage tank 1. At the same time, the rotating sleeve installation of the protective shell 6 enables the drive shaft 5 to rotate stably, further enhancing the mixing effect.

The bevel gear 8 is used to transmit power, realizing the vertical transmission between the stirring rod 7 and the drive shaft 5, making the structure of the mixing assembly more compact and reasonable.

[0025] In a further preferred embodiment of this utility model, a first rubber belt 10 is movably sleeved on the outside of the turning roller 4 and the material distribution rod 17, and a second rubber belt 11 is movably sleeved on the outside of the drive shaft 5 and the material distribution rod 17. Both the first rubber belt 10 and the second rubber belt 11 are used for transmission. Anti-slip sleeves 9 are installed on the turning roller 4, the drive shaft 5 and the material distribution rod 17, respectively, which can contact the first rubber belt 10 and the second rubber belt 11.

[0026] In this embodiment, the design of the first rubber belt 10 realizes the power transmission between the turning roller 4 and the material distribution rod 17, so that the two actions of turning and distributing can be carried out in a coordinated manner. The second rubber belt 11 is also used for transmission. The design of the second rubber belt 11 realizes the power transmission between the drive shaft 5 and the material distribution rod 17, ensuring the synchronous operation of the mixing component and the material distribution component. The anti-slip sleeve 9 can contact the first rubber belt 10 and the second rubber belt 11 respectively, increasing the friction between the belt and the shaft, preventing the belt from slipping during the transmission process, and ensuring the stable transmission of power.

[0027] In a further preferred embodiment of the present invention, the bottom of the dispensing cylinder 2 is provided with a discharge port, the side of the storage box 1 is provided with a replenishment port, the replenishment port is covered with a feeding hopper 12 for guiding the input of heavy metal curing agent, and the isolation plate 18 can contact the inner wall of the dispensing cylinder 2.

[0028] In this embodiment, the discharge port design allows the curing agent to be discharged evenly and quantitatively into the farmland, avoiding waste and excessive concentration of the curing agent and ensuring the uniformity of the treatment effect. The replenishment port is used to replenish the heavy metal curing agent into the storage tank 1. The replenishment port design allows the storage tank 1 to continuously supply curing agent, ensuring the continuous progress of the treatment work. The feeding hopper 12 is used to guide the heavy metal curing agent into the storage tank 1.

The design of the contact between the isolation plate 18 and the inner wall of the distribution cylinder 2 can further enhance the stability of the isolation plate 18 during the distribution process, preventing it from deviating from the predetermined position due to vibration or external force, thereby ensuring the uniformity and accuracy of the distribution.

[0029] In a further preferred embodiment of the present invention, an mounting plate 14 is installed on the storage box 1, an electric telescopic rod 15 is fixed on the mounting plate 14, a moving wheel 16 is installed on the output rod of the electric telescopic rod 15, and a handle 13 is hinged to the side of the storage box 1 away from the mounting frame 3.

[0030] In this embodiment, the mounting plate 14 serves as the fixed base for the electric telescopic rod 15, providing necessary support for subsequent movement and adjustment. The design of the electric telescopic rod 15 enables the telescopic function of the moving wheels 16, thereby allowing the height and position of the storage box 1 to be adjusted as needed, facilitating the movement and positioning of the device, and also making it easy to adjust the soil turning depth. The design of the moving wheels 16 allows the entire device to move easily in the farmland, improving work efficiency and flexibility. The handle 13 makes it convenient for the operator to carry and move the device.

[0031] In a further preferred embodiment of the present invention, the handle 13 is fixedly fitted with an elastic rubber sleeve, the storage box 1 is provided with an observation window 19 for displaying the remaining amount of heavy metal curing agent on the side away from the feeding hopper 12, and a baffle for closing the protective shell 6 is detachably installed on one side of the protective shell 6.

[0032] In this embodiment, the elastic rubber sleeve is used to improve the comfort and anti-slip performance of the operator when holding the handle 13. The design of the elastic rubber sleeve conforms to the ergonomic principle, which can reduce fatigue when holding the handle 13 for a long time and prevent accidents caused by slipping. The observation window 19 is used to display the remaining amount of heavy metal curing agent. The design of the observation window 19 allows the operator to intuitively understand the remaining amount of curing agent in the storage tank 1, so as to replenish the curing agent in time and ensure the continuous progress of the treatment work. The baffle is used to seal the protective shell 6 to prevent external impurities from entering during the stirring process.

[0033] In a further preferred embodiment of the present invention, the soil turning roller 4 is equipped with a plurality of shovel blades for turning soil, and the anti-slip sleeve 9 is provided with a notch for defining the positions of the first rubber belt 10 and the second rubber belt 11.

[0034] In this embodiment, the shovel blade is used to turn the soil and mix the heavy metal solidifier with the soil. The design of the shovel blade allows the turning roller 4 to effectively turn the soil when rotating and distribute the solidifier evenly in the soil, thereby improving the treatment effect. The anti-slip sleeve 9 is originally used to increase the friction between the belt and the shaft to prevent slippage. In this embodiment, the anti-slip sleeve 9 is specially designed with notches. These notches are used to define the positions of the first rubber belt 10 and the second rubber belt 11. The design of the notches ensures that the belt will not deviate from the predetermined path during transmission, thereby ensuring stable power transmission and the reliability of the overall device.

[0035] In a further preferred embodiment of this utility model, a protective film for isolating moisture is pasted inside the feeding port with double-sided adhesive, a storage battery for providing energy to the electrical components is installed on the storage box 1, and a dustproof shell is provided for the servo motor 20.

[0036] In this embodiment, the protective film is used to isolate moisture and prevent it from entering the storage tank 1, thus affecting the quality and performance of the heavy metal curing agent. The design of the protective film improves the moisture-proof performance of the storage tank 1, ensuring the dryness and stability of the curing agent. The battery is used to provide energy for electrical components (such as the servo motor 20). The design of the battery allows the device to work normally without relying on an external power source, improving the portability and flexibility of the device. The dust cover is fitted over the servo motor 20 to prevent dust and impurities from entering the motor and affecting its normal operation. The design of the dust cover extends the service life of the servo motor 20 and improves the overall reliability and stability of the device.

[0037] In summary, compared with related technologies, this device integrates multiple functions such as storage, material piling and discharge, soil turning and mixing, and stirring and dispersing, achieving effective remediation of heavy metal pollution in farmland. By precisely controlling the discharge and mixing of heavy metal solidifying agents, the treatment effect is improved, and the waste and excessive concentration of solidifying agents are avoided. At the same time, the design of the device emphasizes practicality and convenience, such as adjusting the height and position through the electric telescopic rod 15, easily moving the moving wheels 16, and intuitively displaying the remaining amount of solidifying agent through the observation window 19, which improves work efficiency and flexibility. In addition, the device also considers details such as moisture-proof and dust-proof design to ensure the reliability and stability of the overall device, providing strong technical support for the remediation of heavy metal pollution in farmland.
